Utilities charged with delivering reliable power have long endeavored to improve power quality, manage power factor, and maintain voltage levels within allowed limits.Today, with rising penetration of distributed generation (DG) and increasing attention focused on energy efficiency, demand response (DR), and renewable energy integration, the task of managing the distribution network, including voltage and volt-ampere reactive power (VAR) levels, is becoming increasingly complex.At the same time, technological advances in the form of intelligent controls, advanced communication systems, and sophisticated data and analytics solutions are enabling utilities to manage voltage and reactive power as never before. Using intelligent electronic devices and advanced algorithms, utilities can now control voltage and VAR levels in real-time to optimize power flows, reduce energy consumption, and manage challenges that arise with high penetration of distributed energy resources (DER). According to Navigant Research, global annual Volt/VAR control and optimization revenue is expected to grow from $415.0 million in 2017 to $768.7 million in 2026.This Navigant Research report examines the market for Volt/VAR management and optimization technologies.The study focuses on controls for voltage- and VAR-regulating devices (capacitor controls, voltage regulator controls, and load tap changer controls) and the software and analytics systems used to manage and optimize voltage and reactive power levels across the distribution network.It also outlines the major drivers behind demand for Volt/VAR management systems. Global market forecasts, broken out by technology segment, system type, and region, extend through 2026. Finally, the report examines the key technology segments and software system categories related to Volt/VAR management and optimization, as well as the competitive landscape.
